Abbreviation for injured reserve. In professional sports, when a player is placed on the IR, he cannot play for a long time or is considered out for the season. It can also be used informally if someone is injured and can't play sports for a while.

IR is an abbreviated form standing for "Information Revealed". It is usually used after someone says the "TMI" statement telling you that they really did not need to know what you just revealed, but you are proud of sharing your information.
